26.   2x^2 +4x -10 = 0       (-4 + - (root(4^2 - 4*2*-10)))/2*2   =   
(-4 + - (root(96)))/4
(-4 + (root(96)))/4  ≈  1.45
(-4 -  (root(96)))/4  ≈  -3.45
27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore   x -2 = 0    x +3 = 0    x -5 = 0   so   f(x) = 0 when x = 2, -3 or 5 
28. It looks like it shows you how to do it
        
             
        
        
        
<span>3w - 3x + 2w - 6 - 8
Combine like terms:
= 5w - 3x - 14</span>
        
                    
             
        
        
        
A: 6/8, 9/12, 12/16
b: 6/14, 9/21, 12/28
c: 6/9, 2/3, 4/6
d: 1/4, 2/8, 2/12
In order to find equivalent fractions for a fraction is multiply or divide the numerator and denominator by the same number.
For example, 3/4=6/8 because 3x2=6 and 4x2=8, 6/8. 
Hope this helps!
        
                    
             
        
        
        
Well first find the area of the semi-circle. 
If the area of a cricle is equal to pi*radius^2 , then you can just find that and divide by 2.
So, A = pi*2^2. = 4pi
We know that the radius is 2 because the length of the side of the rectangle is 4, meaning that the diameter of the semi-circle is 4, and so the radius is 2 as it is half of the diameter. 
We can easily calculate the area of the rectangle, which is
 Length * width = 6*4 = 24.
Next we divide 4pi by 2 in order to get the area of the semi-circle, giving us an area of 2pi
We can just subtract 2pi from 24 and get the area of the shaded region.
Area of the shaded region (answer): 17.7
